When three-dimensional animation display is carried out in the prior art, the requirement on the hardware performance of display equipment is high by directly adopting a three-dimensional animation frame, otherwise, the animation is blocked, and the user experience is very poor.

The object rendering method provided by the present application is explained in detail below.
Referring to fig. 2, fig. 2 is a flowchart of an object rendering method illustrated in the present application. The object rendering method is applied to the electronic equipment, and when the electronic equipment implements the method, the method can comprise the following steps:
s201, acquiring a two-dimensional image including a rendering object, and determining a rotation track of the rendering object according to a rendering requirement of the rendering object.
In specific implementation, the two-dimensional image in the application can be a UI design image, and the two-dimensional image includes an object to be rendered during display, namely a rendering object, which is also called an object for which the two-dimensional image needs to be displayed in a three-dimensional animation.
In addition, after the two-dimensional image is generated, the animation display requirement (visualization requirement) of the rendering object therein can be determined, so that the rendering requirement of the rendering object in the two-dimensional image can be obtained while the two-dimensional image is obtained, for example, at what position each time is displayed, at what size the position is displayed, and the like. The rotational trajectory of the rendering object may be determined based on the rendering requirements of the rendering object. It should be noted that, the two-dimensional image includes at least one rendering object, and when the two-dimensional image includes a plurality of rendering objects, the rotation tracks of the plurality of rendering objects may be the same or different, and may be determined according to actual situations. For convenience of description, the present application takes an example that rendering objects in a two-dimensional image all correspond to a rotation track.
It is noted that the rotation orbit in this application can be understood as: rendering objects in the two-dimensional image are rotated around a certain center in an orbit of an ellipse, a circle, or the like.
S202, based on the rotation track and the initial position of the rendering object in the rotation track, determining the target position of the rendering object moving according to the rotation track, and determining the scaling degree and the stacking sequence of the rendering object.
The stacking sequence in the application is used for representing the up-down stereoscopic relation of the rendering objects on the stacking sequence.
In practical application, in order to perform three-dimensional animation display, the rendering objects moving along the same trajectory in the UI design drawing fall on the rotation track, and an initial position of the rendering object on the rotation track needs to be determined, so that a next position when the rendering object moves along the rotation track, that is, a target position in step S202, can be determined. For example, when a rendering object is three-dimensionally displayed using a Cascading Style Sheets (CSS), the initial position and the target position refer to positions of the rendering object in the CSS.
In addition, in order to realize three-dimensional animation display, the position of the rendering object is updated in a timed or real-time manner in the embodiment of the present application, so that the target position in the present application can be understood as the position of the next time determined by using the initial position of the current time as a reference.
Specifically, the rendering requirement of the rendering object in the present application includes track parameters of a rotation track, where when the rotation track of the rendering object is an ellipse, the track parameters of the rotation track are a semi-major axis a and a semi-minor axis b of the rotation track, and if the rotation track is a circular track, the semi-major axis is equal to the semi-minor axis, that is, a is equal to b. In a visual three-dimensional animation, generally, a plurality of rendering objects (which may be relatively small) rotate around a center rendering object, the position of the center rendering object is set to (X0, Y0), and referring to an elliptical rotation track shown in fig. 3, (X0, Y0) are central points of the elliptical track, in order to implement a three-dimensional animation display, the rendering objects moving around the elliptical track are placed on the elliptical track, that is, a target position of the rendering objects moving according to the elliptical track needs to be determined.
Optionally, based on any of the above embodiments, step S202 may be implemented according to the flow shown in fig. 4, and includes the following steps:
s401, determining the rotation angle of the rendering object based on the position of the central point of the rotation track and the initial position of the rendering object in the rotation track.
The rotation angle determined in step S401 is the rotation angle at the target position when the rendering object moves at the next time.
In specific implementation, when there are a plurality of rendering objects, the initial position of each rendering object in the rotation track may be determined according to the number of the rendering objects. For example, the position of the rendering object is expressed by abscissa and ordinate, and the initial position of the ith rendering object is marked as (Xi, Yi). When the initial position of the ith rotating object is determined, the initial rotating angle of the rendering object is determined firstly and is marked as theta i An included angle between a coordinate connecting line of an initial coordinate of the rendering object and a central point and a long axis is formed, and then an initial position is determined based on the initial rotation angle; when the initial rotation angle of each rendering object is determined, the initial rotation angle may be determined based on the distribution of each rendering object on the rotation track, and the initial rotation angle of each rendering object may be calculated based on the principle. It should be noted that the initial rotation angle in the present application may be understood as an angle at which the rendering object is located at the current time (initial position).
Optionally, in order to obtain a better display effect of the three-dimensional rendering picture, the rendering objects may be uniformly distributed according to the present application, and the relationship between the initial rotation angles of the rendering objects may be represented by the following formula:
θ i -θ i-1 ＝2*π/N
in the above formula, N is the number of rendering objects, θ i Initial rotation angle, θ, for the ith rendering object i-1 The initial rotation angle for the i-1 th rendering object. Then, the initial position of the ith rendering object at the current initial rotation angle is determined.
When the rendering object is moved according to the rotation track during the timing refresh, the rendering angle of the rendering object may change, and specifically, the rotation angle of the rendering object at the next time may be determined according to the following procedure: the value of the rotation angle is a sum of the initial rotation angle at the present time and a fixed offset amount Δ θ, and is expressed as: theta i + Δ θ. And the offset amount Δ θ can be calculated by the following equation:
where T is the rotation period and n is the timer interval.
S402, determining the target position of the rendering object based on the track parameters and the rotation angle.
In specific implementation, the description is further given by taking the elliptical orbit shown in fig. 3 as an example, the orbit parameters of the elliptical orbit are a major axis a and a minor axis b, the description is given by taking the target position of the ith rendering object as an example, and the rotation angle of the ith rendering object is determined based on step S401 as
The target position of the rendering object can be calculated according to the following formula:
wherein, the (x, y) in the formula is the target position of the ith rendering object, i.e. the position to be selected. And determining the target position of the rendering object at each moment based on the formula.
And S403, adjusting the zoom degree and the stacking sequence of the rendering objects according to the rotation angle.
In specific implementation, the scaling degree and the stacking order of the rendering objects depend on the rotation angle. The stacking order is used to represent the stereoscopic relationship of the rendering object during the display, and may also be referred to as depth of field in the image, or may also be understood as a third-dimensional coordinate, which is denoted as z-index. In three-dimensional space, objects of the same size exhibit the effect of being large and small, and based on this principle, rendering objects presented at the viewpoint should be larger, while rendering objects far from the viewpoint are smaller.
Optionally, based on any of the above embodiments, the zoom level and the stacking order of the rendered objects may be adjusted according to the following procedures:
if the rendering object is determined to be close to the viewpoint based on the rotation angle, the scaling degree of the rendering object is increased to enlarge the rendering object and increase the stacking sequence value of the rendering object;
if the rendering object is determined to be far away from the viewpoint based on the rotation angle, the scaling degree of the rendering object is reduced so as to reduce the rendering object and reduce the stacking sequence value of the rendering object.
It should be noted that the viewpoint in the embodiment of the present application may be understood as a point where the human eye has the best viewing angle and visual effect when viewing the three-dimensional animation.
Specifically, also explained in conjunction with fig. 3, point a0 on the elliptical orbit is considered to be the closest point to the viewpoint. The rotation angle of the ith rendering object
In the process, it is indicated that the rendering object is farthest from the viewpoint, and correspondingly, the size (display size) of the rendering object is the smallest, so that the zoom degree of the rendering object can be reduced to reduce the rendering object, so as to improve the display effect of the three-dimensional animation. When it comes to
When the rendering object is closest to the viewpoint, i.e. at point a0 of the rotation track in fig. 3, the size of the rendering object should be the largest, so that the rendering object may be enlarged by increasing the zoom level of the rendering object. In specific implementation, when the zoom level of the rendering object is increased or decreased, the principle is that the three-dimensional animation display effect of the adjusted rendering object is better.
Optionally, in order to obtain a better display effect, a zoom degree corresponding to each rotation angle on the elliptical track is preset, and after the rotation angle of the ith rendering object is determined, the zoom degree of the rendering object may be directly determined based on the correspondence between the rotation angle and the zoom degree. According to the embodiment of the application, the effect of the near-large and far-small is achieved by adjusting the size of the rendering object, so that the achieved three-dimensional display effect is closer to a real three-dimensional scene.
Optionally, when three-dimensional display is performed, multiple rendering objects are likely to exist, based on the scene, a rendering object close to the viewpoint and a rendering object far from the viewpoint may exist at the same time, and the rendering object close to the viewpoint may block the rendering object far from the viewpoint, and when blocking occurs, the blocking effect is not good, that is, the rendering object close to the viewpoint cannot better block the rendering object far from the viewpoint, so that the playing effect of the three-dimensional animation is affected, and therefore, in order to solve the problem, the three-dimensional display is implemented by adjusting the stacking sequence of the rendering objects. In specific implementation, if the rendering object is closer to the viewpoint, increasing the stacking sequence value of the rendering object, namely increasing the z-index value of the rendering object; and if the rendering object is far away from the viewpoint, reducing the stacking sequence value of the rendering object, namely, reducing the z-index value of the rendering object.
Referring to fig. 3, when the rendering object is closest to the viewpoint, for example, the rendering object at the viewpoint position is adjusted to have a stacking order value z-index larger, so that the adjusted rendering object can block the rendering object farther from the viewpoint, for example, the rendering object at other positions farther from the viewpoint, such as a symmetric point of the viewpoint. Correspondingly, the rendering objects farther from the viewpoint are reduced in the stacking sequence value z-index of the rendering objects farther from the viewpoint, so that the rendering objects closer to the viewpoint can better shield the rotating objects farther from the viewpoint, and a better three-dimensional display effect is achieved. Based on this, by adjusting the stacking sequence value z-index of the rendering objects on the rotation track, the effects of near and far and mutual covering in reality are presented, and the displayed three-dimensional rendering animation is closer to the actual three-dimensional effect.
And S203, performing three-dimensional rendering and display on the rendering object according to the target position, the zooming degree and the stacking sequence of the rendering object.
Specifically, after the target position, the zoom degree and the stacking sequence of the rendering object are determined, when the rendering object is subjected to three-dimensional rendering display, the three-dimensional rendering display can be realized through a Cascading Style Sheet (CSS). In specific implementation, the current position, the scaling degree and the stacking sequence of the rendering object are modified by the CSS to the target position, the scaling degree and the stacking sequence determined in step S202, so that the style of the rendering object can be modified, that is, the three-dimensional rendering of the rendering object is realized. Because the three values of the rendering object are changed in a timing or real-time manner, the rendering object in the UI design can move according to the track of the rotation track, and meanwhile, the three-dimensional animation display is realized. The timing operation is generally implemented by setting a timer at setInterval, which will be described in detail later.
Optionally, based on any of the above embodiments, step S201 and step S203 in the present application are implemented by a main thread. However, in practical applications, due to the single-thread characteristic of JS, when the main thread performs timing calculation by using the setInterval method, if the calculation is time-consuming, other work of the main thread may be blocked, especially in data visualization, there is generally more than one animation component, and if there are other operations on a page at this time, problems such as inaccurate timer and stuck animation may be caused, so in order to solve this problem, the following process is proposed in the embodiment of the present application:
and calling the sub-thread so that the sub-thread determines the target position of the rendering object moving according to the rotation track and determines the scaling degree and the stacking sequence of the rendering object based on the rotation track and the initial position of the rendering object in the rotation track.
In specific implementation, the webworker sub-thread is called to execute the relevant process in the step S202, that is, the target position, the zooming degree and the stacking sequence of the rendering object are determined, and then the three calculation results are fed back to the main thread, so that the resources of the main thread can be effectively saved.
By implementing the object rendering method provided by the application, after the two-dimensional image comprising the rendering object is obtained, the rotation track of the rendering object is determined according to the rendering requirement of the rendering object, then, based on the rotation track and the initial position of the rendering object in the rotation track, determining a target position of the rendering object moving according to the rotation track, and a zoom level and a stacking order of the rendering object when moving, and then three-dimensionally rendering the rendered object based on the determined target position, zoom level and stacking order, thereby directly processing the rendering object in the two-dimensional image, realizing smooth and real three-dimensional animation rendering effect, namely achieving the effect of simulating three-dimensional display based on the two-dimensional image, this avoids the use of three-dimensional frames of the prior art, thereby reducing the requirements for hardware devices and avoiding the waste of resources.
